柴油發電機實質是一臺三次諧波自勵磁凸極式三相四線同步發電機，因具有輸出功率大、適合移動等優點，故廣泛用于廠礦、工程施工等場合。雖然功率不同的發電機，其繞組數據有所不同，但電路連接基本相同：

The diesel generator is essentially a third-order harmonic self-excited salient pole three-phase four wire synchronous generator, which is widely used in factories, mines, engineering construction and other occasions due to its advantages of high output power and suitability for movement. Although the winding data of generators with different powers may vary, the circuit connections are basically the same:

接線過程：柴油發電機出來的四根線。其中一根是N標記的線是零線。別的三根為火線。三相負載平衡。簡單的一點說就是發電機是15KW現在帶了一臺5KW的三相電動機。

Wiring process: Four wires from the diesel generator. One of the lines marked with N is the zero line. The other three are live wires. Three phase load balancing. Simply put, the generator is 15KW and now comes with a 5KW three-phase motor.

假如說想再接一臺2KW的單相電機的話很有可能造成三相不平衡。如果想單獨接單相電用的話可以三根火線中隨便拉一根當作火線。再接一根零線可以當作單相電用。要是想單獨接一相出來用也可以。不過功率是不能太大的設備。那樣容易造成三相不平衡。另外三相柴油發電機還得看多少KW的發電機。小的發電機見意接三相電后。可以接一些照明什么的。不主張再接功率大的電器。

If you want to connect another 2KW single-phase motor, it is very likely to cause three-phase imbalance. If you want to connect single-phase electricity separately, you can pull any one of the three live wires as a live wire. Connecting another neutral wire can be used as single-phase electricity. If you want to connect one phase separately, you can also use it. However, the power cannot be too high for devices. That can easily cause three-phase imbalance. In addition, it depends on how many KW generators there are for three-phase diesel generators. The small generator is connected to three-phase electricity. Can you provide some lighting or something. We do not advocate connecting high-power electrical appliances again.

接線注意事項：柴油發電機組接線時要注意以下幾點：

Wiring precautions: When wiring diesel generator sets, pay attention to the following points:

1、接地線接線點一般是在柴油發電機組的底盤末端，在安裝接地線時，必須接到合適的地線位置。

1. The grounding wire connection point is generally located at the end of the chassis of the diesel generator set. When installing the grounding wire, it must be connected to the appropriate grounding wire position.

2、交流發電機接地中線的連接通常由用戶安裝時決定，當柴油發電機組作為唯一電源時，中線必須直接連到工廠接地線上。

2. The connection of the grounding neutral of the AC generator is usually determined by the user during installation. When the diesel generator set is used as the sole power source, the neutral must be directly connected to the factory grounding wire.

3、較為復雜的安裝，應選擇接地中點以確保柴油發電機組正確的運行或保護設備，例如發現接地故障和將接地循環電流降到最小。

3. For more complex installations, the grounding midpoint should be selected to ensure the correct operation or protection of the diesel generator set, such as detecting grounding faults and minimizing the grounding circulating current.

4、接地線必須根據用戶和地方當局的建議來安排。

4. The grounding wire must be arranged according to the suggestions of the user and local authorities.

5、保證設備接線一直得到有效的維持，關于接線系統的維護應嚴格按照說明書去做。

5. Ensure that the equipment wiring is always effectively maintained, and the maintenance of the wiring system should be strictly carried out in accordance with the instructions.

柴油電機組要做到精確接線，首先應辨別接線柱或引出線是相線仍是零線。通常情況下，發電機的各接線柱或引出線都用必然的標記來區別是相線仍是零線。只要加以重視就可進行辨別零線接線柱常常使用字母M或O作標記，也有在接線旁標以接地符號標示的。

To achieve precise wiring of diesel generator sets, the first step is to distinguish whether the terminal or outgoing line is a phase line or a zero line. Usually, the terminals or leads of a generator are marked with necessary markings to distinguish whether it is a phase line or a neutral line. As long as it is taken seriously, it can be distinguished that the zero wire terminal is often marked with the letters M or O, and there are also grounding symbols marked next to the wiring.

如果零線接線柱上無符號或符號恍惚不清，可在發電機運行歷程中用電壓表測試鑒定，不要采用“碰火”的操作。

If there is no symbol on the zero wire terminal or the symbol is unclear, a voltmeter can be used to test and identify it during the operation of the generator, and the operation of "touching fire" should not be used.
